- a catheter having a proximal end and a distal end;
- a catheter hub in fluid communication with the catheter and having a proximal end and a distal end connected to the proximal end of the catheter and a side port in fluid communication with the catheter hub;
- an introducer needle having a proximal end and a distal end and having a needle hub having a distal end and a proximal end, said proximal end of said introducer needle extending from the distal end of said needle hub, said introducer needle adapted to be positioned within said catheter in an insertion position wherein said distal end of said introducer needle extends distally past the distal end of said catheter, said needle hub being rotatable with respect to said catheter hub and being movable proximally with respect thereto when in said insertion position;
- a seal affixed to the catheter hub and located proximal of the side port, said seal sealing said proximal end of said catheter hub;
- said introducer needle having an opening at said distal end and having a notch located adjacent said side port in said catheter hub when said introducer needle is in said insertion position such that fluid can communicate between said opening at said distal end of said introducer needle and said side port but is prevented from passing out of said proximal end of said catheter hub by said seal.
